The bonds are ionic.
According to the law of conservation of mass how many atoms of calcium can react to produce more calcium?
Calcium contains only one atom per molecule, while oxygen contains two. The usual reaction product from a reaction between calcium and oxygen has the formula CaO and therefore contains one atom of each element per molecule. 4 moles of oxygen provides 8 moles of oxygen atoms, so that under the conditions given, calcium is the limiting reactant, and 6.55 moles of calcium oxide will be formed.

Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
It's the concentration of the acid.Limestone and marble are forms of calcium carbonate.Acid rain reacts with calcium carbonate. The stronger the acid the more quickly it effects calcium carbonate and dissolves.

According to the law of conservation of mass how many atoms of calcium can react to produce more calcium?
Calcium cation is Ca2+ and oxygen anion is O2-.
No. Oxygen is an electron receptor (oxidizer) whereas Ca is a doner.
Hydrogen gas is released when calcium and water react.
No: That would violate the law of conservation of mass and require creation of new atoms, which no chemical reaction can achieve.
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).

Steel and oxygen react together to form rust.

Oxygen is an element - the only thing that composes oxygen are oxygen atoms. Oxygen found naturally (molecular oxygen) is formed from two atoms of oxygen, O2.
Three atoms of oxygen are required to react with each two atoms of aluminum to form the most common product of reaction between oxygen and aluminum. Therefore, 0.75 mole of oxygen atoms will be required to react with 0.5 mole of aluminum atoms. The atomic weight of oxygen is 15.999; therefore, the mass will be (0.75)(15.999) = 12 grams of oxygen, to the maximum possibly justified number of significant digits.
